REMOVABLE PIN-ON BUTTON.

Specification of Letters Patent.

Patented June 20, 1916.

Application filed February 12, 1916. Serial No. 77,912.

To all whom it may concern Be it known that I, ANGELO C. ROVELLII, acitizen of the United States, residing at Philadelphia, in the county ofPhiladelphia and State of Pennsylvania, have invented a certain new anduseful Removable Pin-On Button, of which the following is aspecification.

The principal objects of the present invention are, first, to provide aseparable button which can be readily and, if necessary, repeatedlyapplied to a. garment or the like without marring the same, which whenap plied is firm, strong and practically impossible of accidental orunintended separation, and which can be readily detached by theconvenient separation of its parts whenever it may be necessary ordesirable so to do; and second, to provide a construction, combinationand arrangement of parts which is comparatively easily made andassembled and in which appropriate materials can be used.

One embodiment of the invention is chosen from others for illustrationin th acompanying drawings in which Figure 1, is a sectional view of abutton embodying features of the invention. Fig. 2, is a similar View ofa button embodying a modification of the invention. Fig. 3, is a top orplan view of Fig. 1. Fig. 4, is a top or plan view of Fig. 2. Fig. 5, isa top orplan view of a detached. part of the button, and Fig. 6, is aside elevation, partly in section, of another part of the button on anenlarged scale.

In the drawings 1, is a set of opposed inwardly yieldable spring tonguescarried by the button 2, and adapted to permanently grip and immovablyhold a cylindrical shank 3, against sliding motion in outward directionand to permit of freedom of sliding motion in inward direction. 1, is apin having a needle or like point 5, adapted to repeatedly penetrate afabric, as a, without marring it, and having a cylindrical shank ofuniform diameter adapted to be permanently and immovably gripped by thetongues 1, and having a thread 6 constituting the sole means by whichthe pin can be released from the tongues. Two tongues are shown but thenumber may be increased.

I will now described what I believe to be the best construction for abutton having the structure, characteristics and advantages abovedescribed.

7, is a plate or disk of spring sheet steel or the like and it isperforated as at 8, to provide the tongues 1, and it is also perforatedat 9, to form generally semi-circular concavities in the ends of thetongues. The tongues are formed by what is called 'cracking the piecethat is left between the perforations 8. The ends of the tonguestherefore have a slight inward permanent set. The button 2, is providedwith a seat 10, upon which the disk 7, is seated and also with aconcavity 11, having a hole 12, which serves as a guide when the pin isinserted and which may be of larger diameter than the pin since it neednot engage the later. The disk 7, is held to its seat and againstrotation by means of fingers. As shown in Fig. 2, which illustrates asmall button, the fingers 18, originally projected from the top of thebutton but are bent down as shown and in this instance they are doubledon themselves which increases their strength and rigidity. As shown inFig. 1, which illustrates a large button, the fingers 13, are struck upfrom the base 1 1, of the enlarged part of the button and are bent asabove described. The dotted line 0, indicates the front part or ornamentthat is usually applied to buttons and which forms no part of thisinvention.

In use the pin and button body 2, can be assembled by merely pushing thepin into the body and this is easy because the tongues permit the pin topass between them freely in this direction. The pin does not mar thefabric even though repeatedly pushed through it. The button body and pinare securely held together by the gripping action of the tongues on thepin when an attempt is made to pull the latter out of the button body.The tongues also oppose relative rotation of the pin and button bodysufficiently to prevent their accidental detachment, but these parts canbe relatively rotated, when desired, and when this is done the parts areeasily separated.

It will be obvious to those skilled in the art to which the inventionrelates that modifications may be made in details of con struction andarrangement without departing from the spirit of the invention which isnot limited in regard to such matters or in any way other than the priorart and the appended claims may require.
